write the features of desert and explain the structure of NH3 and. H2o for class 11
Answers
Answer:
The vast majority of the geographic features in the desert include only sand or rocks and gravel. Vegetation, although diverse, is scare. Though there are sand dunes that appear as hills, the lie of the land is flat
Answer
Ammonia is a covalent atom.
The particle is shaped because of the overlap of orbitals of three hydrogen atoms and three Sp3 hybrid orbitals of nitrogen in the structure as the central atom.
The fourth sp³ hybrid orbital is involved by a lone pair.
Due to this the shape of ammonia is trigonal pyramidal.
The H-N-H bond edge is 107.3°, which is somewhat not exactly the tetrahedral edge of 109°28.
This is on the grounds that the bond pair-lone pair repulsions push the N-H bonds somewhat inwards.
In solid and liquid states, ammonia is related through hydrogen bonds.
